Pro-M 75mm Mass Air & 24lb injectors worht it?

Seven · 06-18-2001, 11:52 AM

Has anyone used this on a stock setup? is it worth it? how does this setup effect the EEC?

I have to change my mas air anyway and the injectors have never been changed in 130K on my 94 GT.

the 75mm is a good investment, although you wont notice its potential until you upgrade further. (intake,heads,cam,etc.) the 24# will be overkill but wont hurt anything and if you plan future mods that will require the larger injectors than its probably better to get the mass air meter calibrated correctly now rather than have to change it later.
if its going to be years before you upgrade your heads and other bottleneck items, than you might as well stick with the stock ones until you need something bigger.

From what I've seen on the board, the Pro-M Bullitt 75mm MAF doesn't like the 24lb injectors. Seems like Pro-M couldn't quite get the fuel mapping right with it.

I have the Pro-m 75 with 24lb injectors. You won't notice much of a differenc by itself with a lot of the stock parts still on the car. If you plan on upgrading (heads/cam), then it is probably worth it. I used to have idle surge and stalling problems when it was cold out. I put the stock airbox w/ K&N back in, adjusted my idle (600 - 700 on factory tach), and reset my TPS to .98v, been perfect ever since.
